It depends on your current plan, and the type of plan you're switching to. If you currently have a nonannual plan (billed monthly or every three months), your bill may be prorated. If you upgrade or downgrade an annual plan, you will not receive a prorated refund. See below for details.

Switching Nonannual Plans
When you switch nonannual plans (such as from Web Hosting to Merchant Solutions), we'll refund you a prorated amount for your current plan (based on the number of days remaining within your service period), then determine the prorated cost of your new plan. We'll total these two amounts, then charge your credit card. Your billing date will remain the same.

Example:
Imagine you signed up for a monthly service on the first of the month and pay $30 a month. Fifteen days into the month, you decide to change to a monthly plan that costs $60.

1. You'll receive a refund for $15 (equal to half of your service period) for the unused portion of your monthly service.
2. We'll determine the prorated charge for the new service — in this case, $30 (since there are only 15 days remaining to use the plan).
3. We'll then total these numbers (-$15 + $30), and charge you the sum ($15).
4. Next month, we'll charge you $60, the normal price of your new plan.

Switching from a Nonannual to an Annual Plan
When you change from a nonannual to an annual plan (such as from Web Hosting to Domains), we'll refund you a prorated amount for your current service (based on the number of days remaining within your service period), and then charge you the full amount for your new annual service. You'll see two charges on your credit card, and your billing date will switch to the day you change your plan. Additionally, we'll extend your domain registration for another year.

Switching from an Annual to a Monthly Plan
When you switch from an annual to a nonannual plan (such as from Domains to Web Hosting), we'll charge you the full amount for your new service and extend your domain registration for one more year. We'll reset your billing date to the day you change your plan. Note that you will not receive a refund for the unused portion of your old plan.

Switching Annual Plans
When you switch from one annual service to another (such as from Custom Mailbox to Domains), we'll charge you the full amount for your new service and extend your domain registration for one more year. We'll reset your billing date to the day you change your plan. Note that you will not receive a refund for the unused portion of your old plan.
